Dell R8038 220 W power supply

This Dell R8038 unit delivers 220 W of ATX 12V power. It is built specifically for the OptiPlex GX520 small form factor chassis. A single +12 V rail provides the output required by the original system configuration.

Suits owners replacing a failed original PSU

Buyers needing more than 220 W for upgraded components should look elsewhere. Systems outside the OptiPlex GX520 SFF line will not fit this form factor. The single rail design limits flexibility for high-current add-in cards.

Questions about this item

How much continuous power can the 220 W unit deliver to the +12 V rail?

The supply has a single +12 V rail rated for the full 220 W maximum output.

Does the fan stay quiet when the PSU runs at full load for hours?

The unit uses a standard SFF cooling design; sustained full-load operation will raise fan speed to maintain safe temperatures.
